ROTARY MACHINE.

Specification of Letters Patent resented M529, 1909.

Application filed February 5, 1909. Serial No. 476,268.

To all whom iii-may concern:

Be it known that I, JosEF SvnroH, a sub- 'ect of the'Em eror of Austria,residing at opovicky', in tie Kingdom of Bohemia and Austrian Monarchy,have invented a new and useful Improvement in RotaryMachines,

pass and the objects \of -which of which the ollowing is aspecification.

invention relates to improvements in lime mes having one eccentricalrotary piston, which rotatesin its cylindrical casing so as'to remain ina continual contact with it in a straight line, while the s ace betweencylinder and iston is divide I in two partitions or cham ers by asliding abutment, which moves out. of the way of the piston to let it myimprovements are, first, to maintain a sufiiciently tight contactbetween the sliding abutment and the surface of the cylinder; second, tomakethe pressure of the slidin abutment upon the cylinder continually eastic; third, to attain sufficient durability for the good-working ofthe sliding abutment of said machine. I attain these objects by themechanism illustrated in the Figure 1 is a vertical section of themachine, having an oval piston, and in Fig. 2

an eccentric cy inder the same having a circular piston; Fig. 3 a sideelevation of the machine. I

-3 is the cylinder having the shaft 1 passing centrally throu h it. Thepiston 2 is simply of oval or circular section, fast on the shaft, andworking in contact with the cylinder 3 of the casin at one straightline, which is parallel to t c axis. The induction port 4 and theeduction port 5 are placed to the right and to the left of the slidingplate 6 which is guided by its casing 7 in central direction against thepiston 2; I construct it preferably direct over the axis 1, so that itreposes by its weight upon the rotary piston. Volute springs, or onevolute spring 9 only, sitting on a 'stile 8 which is fastened on saidsliding plate 6 in the middle and in a central direction, is pressing 1tconaccompanying drawing, in sire to secure by Letters Patent, 1s:

tinually'against the volute springs must be divided symmetrically uponthe whole length of the slide, so as to produce a pressure which actsregularly and with the same force at each point of the contact linebetween the sliding abutment and the cylinder. The volute springis'inclosed between a plate 10 upon the stile and-between the cover 12by which the casing 11 of the volute sprin is closed. The casing 11 isfirmly i'ast'ened upon the casing of the machine.

piston. Ifseveral such are pressing at once, they By this arrangementthe contact of the sliding abutment and the piston is continualand anelastic contact accomp grinding between the sliding abutment and therotary piston is produced, whether the piston rotates or not. The effectof it will be a durable tight contactbetweenthe cylinder and the slidingabntmen I do not claim said rotary machines broadly, whether they maybensed as engines or pumps, blowers, motors, or in any other way, but

What I do claim as my invention, and de- A rotary pump for enginescomprising in combination, a stationary member having a cylinder and aninlet and outlet passa e communicating therewith a'nd a. vertica 1y disposed guiding member in alinement with the center of said cylinder andprojecting between said passages through the perimeter of saidcylinder,a rota piston eccentrically mounted in said cylin' er, adownwardly acting vane member disposed in said guiding portions andengaging said piston, a piston sprin and a spring casing secured to saidcylinder for ho ding said spring in engagement with said piston.
